Big money in politics has become a growing concern over the past couple of election cycles. And for good reason.
It's been 120 years, but a U.S. presidential election was bought by the rich and powerful. Back then it was "robber barons" like John D. Rockefeller. Today it's billionaire investors like George Soros.
But the story of the 1896 election shows how easy it is for big money donors to buy an election - even one for the White House.
